ATTACHMENT FOR STEAM COTTON-TRAMPERS.

Specification of Letters Patent.

Patented Mar. 11, 1919.

Application filed November 23, 1917. Serial No.2oac21.

To all whom it may concern: I

Be it known that I, WILLIAM E. SMITH, a citizen of the United States, and a resident of Scotland Neck, in the county of Halifax and State of North Carolina, have invented a new and useful Improvement in Attachments for Steam Cotton-Trampers, of which the following is a, specification.

My present invention relates generally to steam cotton trampers, and more particularly to means in connection therewith to prevent what is at present known as water packed cotton, and to obviate the disadvantages at present well known as incidentthereto, my primary object being the pro vision of simple and effective means whereby to prevent leakage from the piston cylinder of a steam tramper from passing into the press box in which the cotton is compressed.

These ;general objects, and .the advantages, resulting from my invention, as well as the specific construction of the latter in its preferred embodiment, will be better understood from the following description in connection with the accompanying drawing, which latter forms a part of this specification and contains certain figures of which,

Figure 1 is a partial side view illustrating the practical application of my invention.

Fig. 2 is a horizontal section taken substantially on line 22 of Fig. 1, and

Fig. 3 is a partial vertical section taken substantially on line 33 of Fig. 2.

Referring now to these figures and par: ticularly to Fig. 1, I have shown at 10, and in more or less diagrammatic manner, a press box 10 in which cotton is compressed, and into the upper end of which projects the piston rod 11 of a superposed piston cylinder 12, the piston within which (not shown) is connected to the upper end of the piston rod -11 and is actuated by steam, said rod passing exteriorly through a stuffing box in the lower head 13 of the cylinder, the packing of which, being subject to the considerable pressure within the cylinder, is susceptible of considerable leakage, the water of condensation passing downwardly upon the surface of the rod 11 and into the press box 10, causing what is at present known as water packed cotton. 7

'lecting member or plate 14 stationarily mounted between the press box 10 and the cylinder 12 and rigidly connected to the lower head 13 of the latter, by bolts 15,

those portions of which between the upper 7 surface of the plate 1 1 and the cylinder 12 are surmounted by spacing sleeves 16.

The collecting plate or member 14: will have, as shown, a centrally disposed stuifing box 17 through which the piston rod 11 extends, and the gland 18 of which is adjustably connected to the lower surface of the plate 14 by the connecting members 19, it being obvious that the packing of the stuffing box 17 will thus be subjected to atmospheric pressure alone and will therefore effectively act to prevent leakage of water past the same.

The plate or member 14 is further provided with an annular groove 20 in its upper face around the upper portion of the stuffing box 17, which acts as a water collecting chamber to receive the water, and is further provided with a laterally extending discharge pipe 21 which may be carried to any suitable point of disposition, and one end of which communicates with the collecting chamber 20 so as to carry olf the fluid as fast as it is collected therein.

In this Way, it is obvious I may effectively accomplish the desired end in preventing leakage of fluid down the piston rod 11 and into the press box 10, and that such result is accomplished by simple and inexpensive means of great durability.

It is also obvious that in applying this attachment in connection with old installations it is simply necessary to provide a longer piston rod and to block up the steam cylinder a distance above the press box, equivalent to the distance it is desired to have my improvement spaced below the steam cylinder.

I claim:

An attachment for steam cotton tra-mpers of that character having an upper piston cylinder and a lower press box into the latter of which a piston rod depends directly from the piston cylinder, said attachment consisting of a stationary member becharge pipe leading from said chamber to tWeen the cylinder and the press box and discharge collections from piston rod above connected to and supported by said cylinder the member.

said member having a stufling box through WILLIAM E. SMITH. which the piston rod projects, and provided Witnesses:

With a Water collecting chamber in its up J. H. ALEXANDER, Jr.,

per face opposing the cylinder, and a dis- HUGH JOHNSON.
